Abstract
A method for making a surgical article is provided which comprises exposing a bioabsorbable material, e.g., a copolymer derived from a major amount of glycolide and a minor amount of lactide, to a humid environment either prior to coating the material or prior to or following sterilization of the material for a time period and at a temperature sufficient to predegrade the resulting surgical article.
Claims24
A method comprising the steps of
- a) providing a surgical article made from a bioabsorbable material;
- and
- b) subjecting the surgical article to an atmosphere of about 20% to about 70% relative humidity, at a temperature in the range of about 80° F. to about 200° F. for a period of time sufficient to predegrade the material.
An article of manufacture comprising
- a moisture impervious package containing a suture including one or more filaments of a synthetic bioabsorbable polymer, the filaments having been exposed to an atmosphere of about 20% to about 70% relative humidity and at a temperature in the range of about 80 to about 200° F. for at least one day prior to being packaged.
A method of suturing a wound comprising the steps of:
- a) providing a needled suture, the suture including one or more filaments of a synthetic bioabsorbable polymer, the filaments having been exposed prior to being coated to an atmosphere of about 20% to about 70% relative humidity, at a temperature in the range of about 80° F. to about 200° F. for a period of time sufficient to predegrade the needled suture;
- and
- b) passing the predegraded needled suture through tissue surrounding the wound to create wound closure.
